Yes. The article also said that conceptions were highest during Thanksgiving, Christmas and New Year's.
They should do one for military babies, which are very often conceived right after hubby gets home after being deployed a while. Contrarian that I seem to be, my recollection is that my two sons were both conceived right before hubby went away. I always found it funny that, for me, conception occured during times when there generally wasn't much sex on the radar.
